The Schedule referred to inthese Letters Patent and making pax-ft of the same.

in the county of La Porte, and State of Indiana, have invented a new and useful Improvement in Harrows;

clear, and exact description thereof', reference being hal to the accompanying drawings, in which- -Figure 1-is a perspectiye View, and

Figure 2, a front elevation. v

Like letters designate likeparts in all the figures.

The nature of my invention consists in attaching a hand-lever to the rear hinge of a double barrow, and in attaching to the rear outer ends of the barrow two chains, which extend to the hand-lever, and are hooked thereto.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

as in the common harrow, or, if desired, they may be The hingeb is attached to the rear inside ends of the harrow, and is also formed of two pieces, which extend above the cross-pieces of the barrow.

To the rear outer ends of the harrow are secured two chains, C G, which extend up, and are hooked into the hooks d d on the hand-level' B.

In the frame of the hai-row are teeth of the ordinary construction.

\Vhen the harrow is in motion,should one side of it become clogged up, by throwing the lever B to the right, the left-hand slide of the harrow will be raised up, and freed from anything that may have aecnmnlated in the teeth'; 'and by throwing the lever B in the opposite direction, the other side will be raised, 8vo.
